It uses DLC for connection. This is a quote from the manual
"The ScanTool uses state of the art 16 bit technology. It is programmed to interpret the computer signals and provide you with a real time readout of vehicle data. More importantly, the software programs are written to provide you with detailed, full screen readouts of all data."

If you would like to discuss this in depth you can call Actron. They have very good customer service. Their number is 800 228-7667.
